MACHINERY FOR SIZING AND DRESSING'WARPS.

Specification of Letters Patent No. 13,350, dated July 31, 1855.

Figure I, is a perspective view of the dresser. Fig. II, is an end viewof the spool or beam S and shaft Q. Fig. III end view of the lever 16and weight 15. Fig. IV end view of the rolls 5 and 6, section beam 1,and levers. j

The same letters and figures refer to the salne parts in all thefigures.

The principal features `of our invention consist in the self regulationof the friction on the section beams and size rolls by the strain ortension of the yarn or twine to be dressed, and in the manner of makingand running the spools or beams.

The frame A supports the steam cylinder M, loom beam or yarn beam J, andshafts Q, Q. The rolls H and T, are supported by their axles in theframe A. The worms or screws V, are fastened on the shaft O, which issupported by boxes made fast to the frame The worms or screws are gearedinto the cogwheels W, W, the cogwheels are fast to the shafts Q, Q, onwhich is a series of spools or beams S S. The spools or beams areconnected to the shaft Q, by groove and feather or key.' The loom beam Jhas a cogwheel W, secured on one end of its axle, the worms or screws V,V, drive the cogwheels W, the cog wheel turns the loom beam or yarn beamJ, and shafts Q, Q, the shafts carry the series of spools or beams S,the pulley F is fast to the shaft O. To one end of this shaft isfastened a crank or arm X. The rod Z, is

jointed to the arm X, and extends along and is jointed to the rod R. Therod R extends through the guides 27 and 28 and is jointed to the hook orcatch E. The catch is made in a bow as shown in Fig. I and Fig. IV. Bothends of this catch are adapted to it into the ratchet teeth on the rodP. The bow or catch E is adjusted so as to pass clear of the points ofthe teeth on the rod P when the tension of the yarn is right. The rod Pis supported in the guide 8 which is fast on the frame c. One end of therod or connector 17, is jointed to the ratchet rod P and the other endis jointed to the weight 15 which is supported on the lever 16 as shownin Fig. III. To one end of lever 16 is fastened the friction strap 21which extends upward and over the friction pulley 26 of yarn beam 1 andthence down to the frame D where it is made fast. The spools 25 and yarnbeam 1, are supported by their axles in the frame D. The box or trough20 holds the size of color for sizing or coloring the yarns. The frame 7carrying the roll u, and

jointed to the frame c, has its fulcrum opposite the center of the rollL so that the roll u, is free to rise or fall, resting on the yarns asthey pass from the roll I to the roll L. The vertical rod G, is jointedby one end to the frame 7 and jointed by its other end to the catch E,the weight 9` is supported on frame 7 to give the required strain to theyarn when passing from the section beam through the machine to the loombeam. The roll 2 is supported by its axles in the bearings 11. They areto be made fast to the box or trough 20, in such manner that they may bemoved to or from the size roll 6 carrying with them the roll 2 for thepurpose of regulating the distance the twine or cord should pass throughthe sizing to be saturated.

The rocked lever 18 is jointed to the frame c, at a stud 30. There is acut or hole in one end of the lever 18 to receive the 'arm 19 of thelever 16 and the other end of the lever 18 is fitted into a groove orslot in the hub of the friction pulley 10. This pulley 10 turns on theaxle of the roll 6 on which a flange or collar 12 is fastened and facedwith leather or other suitable subst-ance to make friction. The pulley Fcarries the band K and with it the friction pulley 10. This pulleyshould turn fast enough to drive the size roll 6 so that the yarn wouldbe slack between the size roll and loom beam J. The roll 2 and size roll6 are placed apart in order to saturate the twine. The lever 16 has anarm 19 fastened to it extending upward through the lever 18. The lever16 is jointed to the frame c by a stud and works on its joint 32. Theweight 22 is attached to the friction strap 21. This weight should onlybe heavy enough to keep the beam 1 from turning too fast when the weight15 is balanced on the joint 32 of the lever 16, thus keeping the yarnfrom kinking up between the beam and neck reed 4. lVhen the yarn to bedressed has the right strain on it the hook or catch E is kept out ofthe teeth of the ratchet rod by the tension of the yarn th-us leavingweight 15 unmoved as the catch makes its movement, with the arm X rod .eand R. When the yarn is strained o-r too taut it will raise the roll fwand its frame 7 and its rod G and catch E and when the yarn is too slackthe roll u will sink down carrying with it the frame 7 rod G and catchE, so the weight 15 will be moved outward on the lever giving increasedfriction.

If the section beam 1 is full of yarn and the weight g, placed on theframe 7 to give the required strain to the yarn 14 and the dresser atwork, as the yarn unwinds from the beam l, and is wound up on the beamJ, the weight 15 is moved to the left or from the friction strap 21, bythe catch E rod P land rod 17, thus keeping uniform tension upon theyarn, as it is unwound from the beam 1; when the weight is balanced overthe joint 82 of the lever 16, the yarn should not have as much strain onit, the hook or catch E will work in the ratchet rod P and move theweight 15 to the left, the arm 19 and lever 1S by the weight 15 carryingwith them the friction pulley 10. The farther the weight 15 is moved tothe left the harder it presses the friction pulley against the collar orflange 12, thus helping to drive the roll 6. rPhe rolls I u and L may beput in any suitable place between the roll 6 and loom beam J. Theyshould be placed as near the loom beam as can be. When yarn warps are tobe dressed from section beams the beams are placed in the frame D in theusual way, if four in number there should be four neck reeds and foursets of rolls u, L and I, also a set of hooks E, ratchet rods P andweights for each, so that each shed (or section) of warp is kept at oneuniform tension by the weights 15 being moved automatically.

It should be observed that the whole self regulating power or influenceoriginates in the functions of the roll u, it being sustained in itsposition by the tightness of the yarn and being free to act through theorganization above described to increase or diminish the friction asoccasion may require.

As this invention is applicable to all common machines for dressing yarnwarps, twine, and cords it will not be necessary here to describeminutely all the parts and appurtenances which are common and wellknown.

We are aware that other modes of construction and other forms andpositions of the several parts might be adapted to produce the sameresults from the same acting principles; for instance springs may beused instead of weights and screws may be used instead of ratchets andcatches for increasing the power on friction straps. We do not claimthese devices as such, or any of them.

Vhat we claim as our invention and desire to secure by Letters Patent isThe regulation of the speed of the yarn beams and rollers of thedressing frame by the tension of the warp in the manner substantially asdescribed, namely by the combination of the vibrating roller u with therollers L, and I, rod G and the hoo; E or the equivalent thereof, andthese in combination with the ratchet P,levers 16 and 1S, frictionpulley 10, and weight 15, or their equivalents when arrangedsubstantially in the manner described.
